Greetings Team,

​While I haven't worked with IS-IS before but the only disadvantage I've
encountered with OSPF is that it is resource intensive on the router it is
running on which is why only one instance runs on any PE & P device on an
ISP network. OSPF is pretty good in handling the core network routing while
BGP & EGP handle the last-mile routing between PE & CE devices. BGP & EGP
can run on top of OSPF. I came across this *article*
scrolling the web a while back and I still want to find out if am the only
one who thinks its a matter of choice between the two. Although there isn't
distinct 1:1 argument, it's good we discuss it here and figure out why one
prefer one over the other *(consider a huge flat network)**.* What say you
ladies and gentlemen?

Warm regards,

Michael Bullut.
